BRUSH-FIBERCLAIVIP.

SPECIFICATION forming part of Letters Iatent No. 471,606, dated March 29, 1892. Application liled June 4, 1891. Serial No. 395,013. (No model.)

vand I do declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to a new and useful improvement in a brush-ber clamp and separatorespecially designed for folding and di- Viding the brush stock or ber into separate tufts in the operation of securing it in the adjacent circular cells or pockets in the brush block or body, and construction and arrangement of parts, as hereinafter fully set forth, the essential features of which being pointed out particularly in the claims.

The object of the invention is to provide means whereby the brush stock or ber may be folded or doubled upon itself and divided into separate tufts, enabling a series of adjacent circular cells in the body of the brush to be simultaneously lled therewith. This object is attained by the device illustrated in the accompanying drawings, in which- Figure l is a plan view showing the clamp placed over a series of circular cells in the brush-block, the stock or brush-ber lying Lacross a portion of the face of the clamp and crossed by the binding-Wire, which is partly shown by dotted lines. Fig. 2 is a central longitudinal section through -the clamp and brush-block, the upper face of the clamp being covered with the brush-ber, which appears in cross-section, showing the relative position of parts before forcing the berinto the clamp to effect the folding and separation thereof preparatory to securing it in the adjacent cells in the brush-block. Fig. 3 is a perspective view of a portion of the clamp, like parts being broken away. Fig. 4 is a transverse section through the clamp and brush-block, showing the folded ber forced into the cell therein.

Referring to the letters of reference,A designates the clamp, which is made preferably forming an open space through the longitudinal center of the clamp between their inner ends, as clearly shown in Figs. l and 3. upper edges of the. sides orrails ofthe clamp between the partitions b are provided with a series of notches or depressions d, and the upper edge and inner corner of said partitions are beveled to forma sharp point at said corner, as shown at c. The vertical end portions B of the clamp are provided in their inner faces with a groove e, that forms a Way for the binding-wire C, employed to secure the ber or stock F in the brush-block, and also for the traveling blade D, by means of which said ber and Wire are forced through the clamp and into said block.

Edesignates the body orblock of the brush, which is provided with a series of adjacent circular cells d, located at such distance apart Said partitionsare arranged.

The y as to register with the pockets f, formed between the partitionsb of the clamp, as clearly shown in Figs. 1 and 2.

To employ this improved clamp for the purpose indicated, the stock or brush-ber F is placed across the clamp between the uprights B and so that said stock will be equally divided longitudinally and will lie in and above the depressions ct in the sides of the clamp in sufcient quantity to form'the size tufts required to ll the cells CZ in the brush-block, as shown in Figs. l and 2. The binding-wire C is then placed across the stock, the right-angle end portions t of said wire sliding in the ways e in theclamp with the'bent ends extending downward, as shown in Fig. 2. Then the follower-blade D is placed upon the wire, its ends sliding in said ways e, and by any suitable means for the purpose said blade is depressed, doubling the ber in the clamp, whereby it is separated by the partitions h into independent tufts,which ll the pockets f of the clamp, and by means of said follower-blade D are forced down into the corresponding cells d of the brush-block, which is placed below said clamp,

IOO

the Wire C cutting its Way through the wood between the cells d, and the ends t of said Wire being forced through and clinched in the back of said block, thereby firmly securing the separated stock in the adjacent cells in the body of the brush, as clearly shown in Fig. 4. The blade Dl and clamp are thenv removed, leaving the tufts of fiber fiXedly anchored in the block.

The ordinary manner of securing independent tufts of fiber in the adjacent cells in the brush-block has beenl to str in g each tuft upon a strand of Wire, Which is seWed Ythrough the back of the block to retain thetuft in the cell, but one cell being filled at a time. With my improved c lamp'aseries of cells may be iilled simultaneously, effecting economy in the manufacture of, thebrush,enabling.it to made tly atndproducinga brush of superior. i quality. 4

Hating thus.- fillly- Set forth my invention,

`1." A clamp'lforthe purpose specified, composed of` the parallel side rails joined atl their ends, saidrail'sliavin gjtheoppositely-arran ged allel side rails, the vertical end portions joining said rails and having a groove or Way therein, said rails having the laterally-extending partitions, and the notches or depressions in their upper edges between said partitions, substantially as specified.

3. .The combination of the clamp having the parallel rails provided with the lateral partitions, the vertical end portions joining said rails and having the. Ways therein, andl the follower-blade adapted to reciprocate in `said ways, by means of lwhich the fiber, is. folded andseparated Withinthe clamp, lsubstantialiy as specitied.
